IMPROVEMENT IN OIL-STOVES.

Specification forming part of Letters Patent No. 179,542, dated July 4, 1876; application filed May 20, 1876.

To all whom it may concern:

Be it known that I, OLIVER EDWARDS, of Florence, in the county of Hampshire and State of Massachusetts, have invented certain new and useful Improvements in Oil-Stoves; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanyingdrawings, and to the letters of reference marked thereon, which form apart of this specification.

My invention relates to certain improvements on my patent dated April 25, 1876, for stoves for burning hydrocarbon-oils.

In the accompanying drawings, wherein like letters designate like parts, Figure 1 is a side elevation of the stove as constructed for cooking purposes. Fig. 2 is a side elevation of the stove witlrthe heating or illuminating drum attached thereto. Fig. 3 is a plan view of the heating-drum. Fig.4 shows the under side of the heating-drum. Fig. 5 is a plan view of tlietop of the cooking-stove. Fig. 6 shows the perforated chimneys or lines.

My invention consists in certain details of construction and combinations of parts, as

hereinafter described and claimed.

In the drawings, ,A represents the oil-reservoir,which may be made ofcast or sheet metal, as desired, and a is an opening for filling the reservoir. B are zincstandards for supporting the plate B. The standards are formed with shoulders b at their upper ends for the reception of the baseplate of either the cooking or heating drum.

The construction of the oil-stove constitutes no part of my present invention, as the same is fully described and claimed in my patent dated April 25, 1876.

O is the heating-drum, provided with mica, as at c c, to afford proper illumination. The base-plate G is perforated at 0, whereby it may be removably secured to the zinc standards B, and said plate is perforated at d, for the purpose of admitting oxygen to the flame within the drum. The top D is formed 1101- low, and of greater diameter than the heatingdrum, so that an annular flange projects over the wallofthe drum. The lower plate Doftop D is provided with perforations (1, or openings between it and its cap, through which a portion of the heated air passes downwardly toward the base or floor, instead of rising directly up, causing the hot air to pass downward before ascending, instead of being allowed to pass away unused. The outer edge of the hollow top D is perforated at e, to establish an outward current of heated air, to heat that portion of the top that projects beyond the wall of the heating-drunr Studs or pins are secured to the upper plate E of top I), and serve to sustain any vessel clear from contact with the upper plate, while the heated air from the drum has free access to such vessel through the perforations c in the upper plate E.

In a heating-stove constructed as above described the heat generated by the hydrocarbons is most eifectually utilized, as it'is first deflected against the inner surface of the drum. It then passes upwardly, and flows into the hollow top, from which a portion of the heat is forced to take a downward course. Another portion of the heat passes out through openings in the periphery of the top, and thereby imparts heat to that part of the top which pro jects from the heating-drum, while the remaining portion of heat generated flows upwardly through the perforated plate, and may be thereafter utilized for warming or cooking purposes, as heretofore set forth.

In order to readily convert the heating-stove into a cooking-stove I construct a cylinder, F, with a base-plate, G, provided with holes f, arranged to register with the zinc standards B, and, by removing the heating-drum, the cooking-drummay be readily placed on, and secured to, the oil-stove. Chimneys or flues H, corresponding in number and size to the wicks used, are arranged within the cookingdrum F, and said fines are perforated at h, to

' admit oxygen to the flame at the point of combustion, the air entering the drum through pertorationsin the base-plate G. The upper edge of the cylinder or drum Fis formed with projections j, which serve as supports for any vessel when but a single vessel needs heating. To provide for the heating of two or more vessels, I place the hollow perforated top J, of cast or sheet metal, on the cookingdrum, and said top J is formed with two or more openings, K, in which kettles or other receptacles are placed. Each opening K is furnished with a perforated cover or lid, L, and about each opening the top is perforated, as at Z, whereby the heated air is effectually disposed over the entire surface of the hollow top as it takes its exit from the cooking drum or cylinder.

The cooking-stove may be thus used to heat one or more vessels, and may be readily converted into a heating-stove by simply removin g the cooking drum or cylinder and replacing the heating-drum.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is V r 1. The combination, with the cooking-drum of an oil-stove, of a hollow perforated top, having a depending flange for its attachment to the drum, and provided with openings for the reception of two or more kitchen utensils, and with covers or lids for said openings, substantially as and for the purpose set forth.

2. The combination, with the heating drum 0 of an oil-stove, of a removable hollow top,

forated upper plate, provided with studs or pins, substantially as and for the purpose set forth.

5. In an oil-stove, a removable hollow top,

perforated about two or more openings adapt-- ed to receive kitchen utensils, substantially as set forth.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.

OLIVER EDWARDS.
